Definitions

  • the invention relates generally to a gear drive apparatus having a pinion gear member and more particularly to a gear drive apparatus having a pinion gear member for use in vehicle window regulators or seat lifters.
  • Automobile window raising and lowering devices usually include a gear train driven by rotation of a handle wherein the gear train operates a linkage that is connected to a window support.
  • a driving plate is keyed to a pinion.
  • the pinion In use of such a mechanism there is a tendency for the pinion to twist with respect to the remainder of the drive mechanism resulting in points of high stress concentration which often results in the fracture of a gear tooth.
  • a gear drive apparatus includes a rotatable drive shaft, a driving member, a driven member and a pinion gear.
  • the rotatable drive shaft contains a handle and a stem.
  • the driving member is integrally connected to the stem and rotates with the stem in response to the rotation of the handle.
  • the driven member is coaxially positioned about the stem and engages the driving member. At least one radial aperture and radial groove are coaxially formed on the driven member and rotated about the stem.
  • a pinion gear is rotatably mounted on the stem and includes at least one radial boss and pinion teeth, which extend from the pinion gear.
  • the gear drive apparatus may include an arcuate slot formed in the driving member and a projection lug extending from the driven member which is seated within the arcuate slot.
  • FIG. 1 is a sectional view of a conventional gear drive apparatus for raising and lowering vehicle windows
  • FIG. 2 is a sectional view taken along line II--II of FIG. 1 and showing the disposition of the braking spring within the conventional gear drive apparatus;
  • FIG. 3 is a plan view showing a driven member of the conventional gear drive apparatus of FIG. 1;
  • FIG. 4 is a sectional view taken along FIG. IV-IV of FIG. 3 and showing the conventional driven member of FIG. 1 engaging a pinion gear;
  • FIG. 5 is a top plan view of the driven member and the pinion gear of the present invention.
  • FIG. 6 is a sectional view taken along line VI--VI of FIG. 5;
  • FIG. 7 is a bottom plan view showing the driven member with the pinion gear
  • FIG. 8 is a sectional view taken along line VIII--VIII of FIG. 5;
  • FIG. 9 is an enlarged side elevational view partially in section of the boss portion and the toothed portion of the pinion gear engaging with a groove and an aperture of the driven member;
  • FIG. 10 is a plan view of a tooth portion of the gear fitted within the radial aperture looking in the direction of the arrows X--X of FIG. 9;
  • FIG. 11 is a plan view of the radial boss positioned within the radial groove looking in the direction of arrows XI--XI of FIG. 9.
  • the driving apparatus 10 typically includes a base plate 11, a casing 12 fixed thereon and a driving shaft 13 rotatably supported on the base plate 11 and within the casing 12.
  • the driving shaft 13 includes a handle 13a and a stem 13b.
  • a driving member 14 and a driven member 15 are coaxially disposed within the casing 12.
  • the driving member 14 is integrally connected to the driving shaft and the driven member 15 is rotatably supported around the driving shaft 13.
  • An arcuate slot 14a is formed on the driving member 14 and a projection lug 15a of the driven member 15 extends within the arcuate groove 14a as shown in FIG. 2, enabling the driving member 14 to rotate the driven member 15.
  • a pinion gear 17 is secured to the driven member 15 and engages a driven member 18, which is connected to a window regulator arm (not shown).
  • a torsion or braking spring 16 is seated around the driving member 14 and includes end portions 16a, 16b which are disposed within the arcuate groove 14a of the driving member 14 and the projection lug 15a of the driven member 15.
  • a peripheral surface of the braking spring is frictionally connected to an inner surface 12a of the casing 12.
  • the gear driving apparatus 10 is actuated by rotation of the driving shaft 13, thereby rotating the driving member 14.
  • the arcuate slot 14a engages one of the end portions 16a, 16b of the braking spring 16 to rotate the driving member 14.
  • the braking spring 16 is drawn toward the driving member so that the peripheral surface of the braking spring 16 separates or releases from the inner surface 12a of the casing 12.
  • the pinion gear 17, which is coaxially provided on the driven member 15, rotates around the driving shaft 13. Further, rotation of the pinion gear 17 drives the drive gear 18 to raise and lower a window, for example.
  • the weight of the window will cause the pinion gear 17 to rotate through the driven gear 18.
  • the projection lug 15a of the driven member 15, which is integrally fixed to the pinion gear 17, abuts one end of the end portion 16a, 16b of the braking spring 16.
  • the peripheral surface of the braking spring 16 engages the inner surface of the casing 12.
  • the present invention corresponds in general to the conventional apparatus depicted in FIGS. 1-4.
  • the pinion gear 17 of the present invention includes a radial boss portion 17a and toothed portion 17c, which extend radially outward to form the pinion gear 17.
  • the driven member 15 is coaxially mounted about the stem 13b and includes a support section 15b having slot or radial apertures 15c and radial grooves 15d, which are coaxially formed in the support section 15 of the driven member 15.
  • the driven member 15 is embossed to form embossments 15e and the radial grooves or gear shaped cavities 15d.
  • Each radial boss portion 17a is positioned or keyed within individual radial apertures 15c.
  • a portion of each toothed portion 17c is separately fitted within radial grooves 15d.
  • a plurality of boss portions 17a and toothed portions 17c may extend radially for individual engagement with the radial apertures 15c and the radial grooves 15d, respectively.
  • the present invention may include a retainer portion 17b, to restrict the movement of the pinion gear 17 along its longitudinal axis.
  • each toothed portion 17c engages within the radial groove 15d and stress is distributed along the entire radial length of each toothed portion 17c. Consequently, stress is more evenly distributed about the toothed portion 17c thus improving the mechanical strength of the pinion gear 17.
